The effects of substituents on the 5J long‐range spin‐spin coupling constants in substituted benzaldehydes

Mostrar todas las versiones(2)

Proton magnetic resonance spectra of several mono‐ and disubstituted benzaldehydes were studied using CW, INDOR and double resonance techniques. It was verified that substitution in the para position has no effect on the long‐range coupling of the aldehydic proton with the ring protons five bonds aw...
